Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: invention relates to oil industry and can be used for implementation of water and gas impact at increasing oil recovery of formations. Method of water-gas impact on formation includes formation of ejector of fine water-gas mixture with foam-forming surfactants and subsequent pumping of obtained mixture by booster pump to injection wells. At the output of the booster pump, the flow of the formed mixture is divided into two parts, one of which is directed directly into the injection wells, and the second one is discharged into the additional contour of ejection of water-gas mixture to increase its gas content with subsequent return of the formed mixture to the input of the booster pump, wherein the supply of the booster pump by liquid is set more than the supply of the power pump. Formation system comprises a power pump, a first ejector whose output is connected to the booster pump input, a vessel with foam-forming surfactants, lines of water supply to power pump, water injection, gas pumping, SAW supply and water-gas mixture pumping to pressure wells with controlled valves installed on them, receiving chamber of the first ejector is communicated with the gas pumping line and with the foam-forming surfactant feed line, and the water injection line is communicated with the first ejector nozzle. In the system the second ejector is installed, and at the output of the booster pump there installed is the water-gas mixture flow divider with discharge lines, one of which is interconnected with the water-gas mixture pumping line to the injection wells, and the other one is connected to the second ejector nozzle, the receiving chamber of which is interconnected with the gas pumping line, and the outlet is connected to the booster pump input. 
     EFFECT: providing control of gas content of water-gas mixture in reservoir conditions to values ensuring maximum possible increase of oil displacement coefficient by optimization of gas fraction in water-gas mixture pumped to injection wells.

Abstract: Изобретение относится к сельскому хозяйству, в частности к кормопроизводству, и может быть использовано в фермерских хозяйствах для термообработки, измельчения и обеззараживания первичного сырья. В процессе приготовления комбикорма подготовленное к переработке первичное сырье перемещается посредством нагнетательного шнека и накапливается в резонаторной камере. Сосредоточение и постоянный подвод первичного сырья в ограниченное пространство резонаторной камеры приводит к ее заполнению и повышению в ней рабочего давления. После заполнения резонаторной камеры включается источник СВЧ-излучения. Первичное сырье подвергается эндогенному нагреву, в результате чего происходит быстрое увеличение его объема, а также повышение давления и температуры в резонаторной камере. Колебание молекулы воды с большой скоростью приводит не только к уничтожению болезнетворных паразитирующих микроорганизмов, но и к разрушению (реструктурированию) первичного сырья или, конкретно, микронизации зерна. Реструктурированное сырье под давлением от увеличенного объема и парообразования удерживается нагнетательным шнеком в резонаторной камере, поскольку винтовая поверхность над камерой осуществляет подачу сырьевой массы сверху вниз, а винтовая поверхность под резанаторной камерой - снизу вверх. Дальнейшее поступление первичного сырья в резонаторную камеру и его эндогенный нагрев способствует принудительному перемещению уже реструктурированного сырья к выгрузному желобу по специализированному каналу, представляющему собой систему вырезов - секторных окон на винтовой поверхности нижний части нагнетательного шнека. В каждом секторном окне вторая по направлению вращения нагнетательного шнека кромка является режущей. Использование группы изобретений позволит повысить качество готового продукта. 2 н.п. ф-лы, 2 ил.
